This invention relates to the field of welding technology and provides a welding device and its working method for component connections. The device includes a worktable, a welding robot mounted on the top of the worktable for welding components, and a positioning component mounted on the top of the worktable. The positioning component includes a limiting mechanism that slides on the top of the worktable. This device solves the problem of welding defects caused by surface flatness defects and dimensional tolerance fluctuations in the components to be welded, resulting in poor contact of the docking reference surface, uneven gaps, and misalignment of the assembly reference. The device reduces sliding resistance by setting up a retaining tube mechanism around the four corners of the inner wall of the frame, using a wheel with a tapered section to roll and contact with the edge of the second component. Real-time data acquisition via a micro-motion sensor and closed-loop linkage of a bidirectional cylinder with the control system compensates for wheel wear, corrects the component sliding posture, ensures the verticality of the second component's vertical sliding, avoids docking deviations, and improves the docking accuracy and welding consistency of the components.
